NISAR Simulated Raw Data

An overview of UAVSAR's flight paths, and the NISAR simulated data that can be accessed in the database.

Simulated NISAR raw data products are generated from UAVSAR data to emulate NISAR data characteristics in order to help users test their algorithms and get a sense of the quality of future NISAR products.

Products Derived from Other Missions in NISAR Format

Sentinel-1 Interferogram (BETA) products are prototype Level 2 NISAR-Format interferometric products (link) produced using the ARIA Science Data System under development for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission. The creation, discovery, and distribution of these products is to inform the NISAR mission team of possible cloud-based processing and data management solutions. As such, these prototype products are not part of the ASF long-term archive and may become unavailable at any time as new SAR interferometric processing and delivery methods are explored.

Other Data Sets of Interest

This dataset is the first-of-its-kind spatial representation of multi-seasonal, global SAR repeat-pass interferometric coherence and backscatter signatures. Global coverage comprises all land masses and ice sheets from 82 degrees northern to 78 degrees southern latitude. The dataset is derived from high-resolution multi-temporal repeat-pass interferometric processing of about 205,000 Sentinel-1 Single-Look-Complex (SLC) data acquired in Interferometric Wide-Swath mode (Sentinel-1 IW mode) from 1-Dec-2019 to 30-Nov-2020.
